Grade 11 physics: SPH3U1-01 | Physics Lab Report | Specific Heat Capacity of Brass | | Jin Jin Shi | 2012/12/6 | Instructor: Mr. Nailer | I. Introduction The amount of heat required to raise the temperature of a solid body depends on its change in temperature (ΔT), its mass (m), and an intrinsic characteristic of the material forming the body called specific heat (cp). The heat is calculated from the equation II. Purpose The purpose of this laboratory is to determine the experimental quantities of heat transfer and specific heat capacity in a laboratory situation.. III.

Determine the percentage error for the calculation using the percentage error equation. %error=accepted value –measured value/accepted value x100% =3.8x10^2-8.7x10^2/3.8x10^2x100% =129 5. Use the equations Q = mcââ€" ³T and Qreleased + Qabsorbed=0 to calculate the specific heat capacity of the unknown metal. Qwater = cp waterx mwater x ΔT water Qwater=Q unknown metal Cp unknown metal=Q unknown metal/m unknown xΔT unknown metal Qwater=(4.18x10^3)(0.1)(84-98) =-5892 Cp unknown metal= -5892/(0.1)(37-98) =9.7x10^2J/kg °C VII. Analyze and Evaluate (a) Consider the percentage difference obtained in Part A. What might have caused this percentage difference? The equipment we were using might may caused this percentage difference, because thermometer might not be accurate when we look at by our eyes, we can ignore this error by using calorimeter. (b) Consider the percentage error obtained in Part B. What may be responsible for the difference in the values between Part A and Part B? The temperature of water might cause the difference in the values between Part A and Part B, because we need Q water in both Part A and Part B, If the temperature of water is different, then the result will also be different. (c) This investigation would be valuable toShow MoreRelatedPhysics Lab Report717 Words   |  3 Pages (g) The steps (c) and (d) were repeated to obtain new values of Ã…Å"e and then step (e) to obtain a new curve III. The process was repeated till reasonably accurate values of F and P were obtained. However, it was seen that the third trial did give sufficiently accurate values, for all practical purposes. To obtain the safe pile capacity, a factor of safety of 2 on the ultimate skin friction resistance and 2.5 on the ultimate point bearing resistance was applied. 1.3.6 The same graph was also solvedRead MorePhysics Lab Report3601 Words   |  15 PagesABSTRACT: The lab of one dimensional motion is a series of experiments that deal with different types of motion in a single direction. In the first experiment, one dimensional motion of a small cart on an air track is measured in a one photogate system. The acceleration was calculated by the infrared light emitting electrode of the photogate sensing the slacks on the picket fence. The calculation for gravity yielded 9.63 m/s^2, which is consistent with the accepted value of 9.8m/s^2. In theRead MorePhysics Lab Report Impulse1163 Words   |  5 PagesImpulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum, our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity, we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track, a timerRead MorePhysics Speed of Sound Lab Report743 Words   |  3 PagesSamantha Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab, we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe, 2) measure the length of a closed-pipe resonator, and 3) analyze the data to determine the speed of sound.

This is shown when a period of oscillation is seen to be independent of the mass of the mass ‘m’. Theory A simple pendulum consists of a mass that is attached to a string of length ‘L’ that is fixed to a point, in this case, a cork suspended by a clamp stand. This allows theRead MorePhysics Lab Report - What Keeps a Stopper Moving in a Circle948 Words   |  4 Pagesthe error associated with calculating the speed of the stopper. In other labs you have used multiple data runs and averaged the data to minimize the random error associated with measuring. Why did you not have to do that on 5. To get the most accurate time we had the person timing also count the revolutions of the stopper. And we didn’t have to do multiple data runs because the time is the least important In this lab we found that the variables of circular motion are directly related. We accomplished
